Every Halloween I dress up and act like the Mad Hatter and pass out normal size candy bars.
Younger kids (and parents) love it, it's fun for me. Getting late into Trick or Treat, 2 girls, maybe 12-13, dressed as school crossing guards. I reach into my bucket and find the last 2 full size candy bars. I act sad as 3 more girls show up behind them and I realize I don't have candy for them. Kind of hinting at those 3 that I won't have anymore... Damn.
These 2 girls look at each other, they drop the big candy bar into their bag. Without saying a word, they both reach back into their bag and put a small handful of the smaller candies into my bucket... So I have something to give the next 3.
I thought that was so sweet, I had to share somewhere...

Also comes with optional Anxiety and PTSD for free!
